The Micronesian fauna of Lauxaniidae, continuing from the first paper in 2009, is supplemented by three species: two new species, Kerteszomyia guamensis, n. sp. and Meiosimyza carolinensis, n. sp. are described, and one Oriental species, Trypetisoma octopunctatum Malloch, is reported for the first time.

Fifty-three species in six families occur in Micronesia. Kevan (1987) listed forty-three species, 20 of which were given as new but undescribed. Kevan (1990) listed eight species as introduced, seven of which were on his previous list, plus Mecopoda elongata (Linnaeus). Seven new species were described in the Conocephalidae, Phisidini, by Jin & Kevan (1992). Eighteen additional new species and a subspecies are described in this paper, seventeen by Vickery & Kevan and one by English & Kevan, nine in the Gryllacrididae: Niphetogryllacris marianae, N. tolensis, Anancistrogera palauensis, Neanias ogasawarensis, Prosopogryllacris palauensis, P. chuukensis, Melaneremus marianae marianae, M. m. rotaensis, M. saiensis, and M. kosraensis; two in the Rhaphidophoridae: Rhaphidophora ponapensis and Stonychophora palauensis; three in the Phaneropteridae: Casigneta palauensis, Isopsera yapanese and I. palauensis; one in the Mecopodidae: Ocica ponapensis English & Kevan; and three in the Conocephalidae: Spinisternum palauensis, Macroxiphus globiceratus and Salomona ponapensis. Nine species are added to the lists of Kevan (1987, 1990), including one described as new. Twenty-six species are known to be endemic in Micronesia.

The Micronesian fauna of the genus Homoneura (Diptera: Lauxaniidae), comprising 18 species, is presented. Seven new species, H. bibaculigera, carolinensis, denticulimentula, longisetosa, notabilis, palauensis and prisca, are described, and six Oriental, one Polynesian and one Australian species are recorded for the first time. A key to the species is given.
